Attenuators Procurement Notes

Verify the specific part number SA18H-04 against official Fairview Microwave documentation to confirm current manufacturing status and technical specifications. Ensure compatibility with system requirements regarding connector gender, power ratings, and frequency limits before procurement. Cross-reference datasheets for any recent updates to material composition or operational parameters.

Attenuators Selection Notes

Select this component when a 4 dB fixed attenuation value is required within an 18 GHz bandwidth. The SMA connector type dictates interface compatibility with existing cabling and equipment. Consider the 2 Watt power rating and stainless steel construction for applications demanding moderate power handling and robust physical protection in varying thermal environments.

Attenuators Part Context

This model belongs to the SA18H series of connectorized attenuators manufactured by Fairview Microwave. The series offers various attenuation values while maintaining consistent SMA connectivity and high-frequency performance up to 18 GHz.
